GASOLENE' OR OIL VENDING MACHINE Specfication of Letters Patent.

Patented Api-.21, 1914.,

Application filed April 22, 1913. Serial No. 762,905.

To llmlom it may concern Be t known that I, WARREN L. CooPER, a

citizen of the United'. States, residing at 'Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Gasolene or Oil Vending Machine; and I do following to be a full, clear, and exact description' of the invention, a the art to which itappertains to make and usethe hereby declare the such as will enable others skilled in same.

ing machines,

and the like.

As an object of the invention, it is the am to provide a coin controlled mechanism, comprislng in conjunction with an oil tank including a pump of any conventional form, adapted to be released, upon depositing a coin in said coin controlled mechanism, in order that the pump may be actuated, so that various quantites of gasolene, oil or the like may be disbursed from the tank.

Another object of the invention is the provision of a machine or apparatus of this character, adapted to be located at different places along the road or the like, whereby a chaufteur, upon depositing a coin in the machine, such as a quarter, may purchase a new supply of gasolene, say for instance, a gallon or more, it depending upon the denomination of the coin, but however, always a gallon.

In order to var the quantity of gasolene, oil or the like, tat is, over a gallon, the pump rod, whichis in the form of a rack bar s providedwith means adapted to contact with a gear wheel of the pump 1necha-` nisin, in order to limit the downward movement of the pump` rod or plunger. This means may be adjusted, thereby regulating the plunger rod or rack bar in its movements downwardly, in order to vary the disbursement of gasolene or other fluid.

In practical and commercial fields the minor or auxiliary details of Construction may be subjected to alterations, to which the patentee is entitled, provided the alterations fall within the scope of what is claimed. i

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings:-Figure 1 is a View in side elevation of a gasolene tank including sufi'icient showing of a pump nechanism, With the improved con controlled nechanisn as applied. F ig. 2 is an enlarged sec-4 tional view of the coin controlled nech'ansm. F ig. 3 is a sectional view on line 3-3 of F ig. 2, showing a portion of the pump rod and part of the tank. Fig. 4 is an enlarged View in elevation of a portion of the mechansm for Operating the pump rod, showing the coin controlled tilting mechanism disf posed in a dilferent position to that shown This invention relates'to the art of vendv and particularly to a coin controlled machine for vending gasolene, oil* n Figs. 1 and 2.

showing a part of the casing for the spring motor. Fig.' 7

s a sectional view on line 7 -7 of Fig. 2, 'showing how the adjustable dog is mounted upon the pump rod or rack. Referring more particularly to the drawings, 1 designates the usual form of gasolene tank, adapted to contain a complete pump (not shown) which, when the pump rod is forced downwardly disburses gasolene from the outlet tube at 2, as shown in F ig. 1. The only portion of the pump that is shown is the pump rod (whichis in the form of a rack bar 3) and which is the essential feature of the pump, that is, in so far as this particular invention is concerned. i Mounted upon the casing 1 is a Supplemental casing 4, in which the usual or conventional form of spring motor 5 and coin box 6 are arranged. The driving shaft 7 of the spring motor is provided with a disk wheel 8, and a crank arm 9. Pivoted to the casing of the motor on the rod 10 is a tilting member 11, one end of which terninates in a coin trougl 12, while the other end terminates in a very resilient or flexible blade 13 having an outwardly and downwardly extending arm 14, to engage a notch 16 of the disk 8, to prevent the motor from operating. Substantially the extreme portion of the blade 13 is disposed beneath the bar 17 of the casing of the motor, thereby holding the trough end of the member 11 up. However, the blade 13 is just flexible enough to respond to the weight of a coin in the trough 12, say for instance, a quarter, but in the present application nothing less than a quarter. However, by a'djusting the bar 17 in the slots 18, in the direction of the arrow a, it will necessitate a coin or coins of greater weight than that of a quarter to cause the blade to bend or respond in an upward direction, whereby the arm 14 may be lifted from the notch 16, for instance, f it 1S desired to obtain' thirty-five cents worth of gasolene, the bar 17 may be adjusted in the direction of the arrow a, so that the weight of the quarter will not tilt the member 11 immediately. Then by droppng ten cent-s in the trough 12 and gradually movng the bar in a reverse direction of the arrow a, untilthe combined weight of the dime and quarter will tilt the member 11, until the spring blade bows sufciently to lift the arm 14 from the notch 16, thereby sett ng the motor into operation. This operation and feature of the invention is only necessary when gasolene is being disbursed by machines ot' this nature at a price of thrtyfive cents per gallon. After the coin is deposited in the trough 12 subsequently to passing through the chute 20 (which s of an irregular shape with the mouth end thereof ofi'set from alinement with the trough 12) the same falls in the coin box 6.

Pivoted to the crank arm is a rod 21, which is guided in an opening 22 of the casin 4.

1`he pump rod or rack 3 meshes with the gear 23 mounted upon and movable with the shaft 24, which is mounted in bearings of the plates 25, 26 and 27 of the frame 28, which is Secured to the casing 4 by the bolts 29. The plate 27 is braced by the bar 30. The pump rod or rack bar 3 is held in mesh with the gear wheel -20 by the lugs 31.

Adjustably secured on the rack bar or pump rod is a oollar dog 32 by means of the set screw 33. This collar dog is so constructed that its'nose 34 is adapted to engage the teeth of the gear 23, in order to limit the pump rod or rack in its downward movement. In other words, if the collar dog is set, so that upon downward movement of the pump rod or rack the gallon of gasolene is disbursed, and it is desired 'to set the machineso that a greater uantity of gasolene may be disbursed, the co lar dog may be adjusted to a higher position on the rack bar, and then as the rack bar lowers it will move a greater distancedownwardly, thereby disbursing the corresponding quantity gasolene or other oil. In this regard the gear rotates or makes more than one revolution.

Mounted upon the transverse pin 34 in the trame 28 is a rockable member 35 having a weight 36. *This rockable member is provided with arms 37, 38, 39 and 40. The arm 38 is provided with a dog or pawl projection 41, which, it will be seen upon referring to Fig. 2, prcvents the gear 20 from being rotated in the direction of the arrow b, but will permit the gear to be rotated in the direction of the arrow c, that is when the rack or pump rod is in its upper postion with the rollar dog out of engagement with the teeth of the gear 20. The arm 39 is likewise provided with a dog or pawl projection 42, which upon referring to Fig. 4 will permit the gear to rotate in the direction of the arrow b, but not in' the direction of the arrow c, that is, not until the arm 44 springs by the stati'onary arm 45 of the plate 26 of the frame 28, so as to contact with the arm 40 of the rockable or tiltable member 35, so as to instantly tilt it to the position shown in Fig. 2.

'When first depositing a coin in the machine, the various parts are arranged as shown in Fig. 2 or Fig. 1, with the rack bar or pump rod iii its downward position, and the rockable member arranged with the dog 41 engaging the teeth of the gear 23. After .the coin has fallen in the trough 12, and remains there long enough to cause the spring portion 13 of the member 11 to bow upwardly, in order to lift the arm 14 from the notch 16, thereby releasing the disk 8, the motor will be set into operation. By virtue of the crank arm 9, the rod 21 will be moved upwardly, until its upper end Contacts with the arm 37 of the rockable member 35, sufficiently to disengage the dog 41 from the teeth of the gear 23 and tilt the member 35 to the position shown in Fig. 4, thereby unlocking the gear 23. The gear 23 is then free to be rotated in the direction of the arrow I), so as to raise or reciprocate the rack bar or p'ump rod vertically to its uppermost position as shown in Fig. 4. To rotate the gear 23 in the direction of' the arrow b, the crank handle 47 is manipulated. As the rack bar or pump rod approaches its uppermost position, the spring arm 44 (which is stationary with the rack bar) Contacts with the arm 45, and upon the rack bar reaching its uppermost position, the spring arm 44 quickly springs by or past the arm 45, and instant-ly tilts the rockable or tiltable member 35 back to the position shown in Fig. 2, but in this instance the collar dog is as shown in Fig. 4, and the rockable member in the position shown in dotted lines in Fig. 4. hen the rack bar or pump rod is in its uppermost position, the gear 23 is then free to be rotated in the direction of the arrow c, and upon rotating said gear 23 in such direction, the pump rod or rack will be lowe'ed, and upon lowering of the same, the )iston of the pump rod or rack will force or isburse gasolcne or other oil from the outlet 2 of the tan-k.

From the foregoing it is to be noted, there has been devised a novel, simple and efiicient coin controlled mechanisn, comprising in conjunction with an oil tenk includin a pump of any conventional form, adapte to be relased, upon depositing a coin in the coin controlled mechanism, in order to actuate the pump, whereby disbursements of quantities V of gasolene may be performed, and one which cluding a pump mechanism therefor having a rack pump rod, a manually operated gear for actu'ating the rack pump rod, a tiltingmember having an arm to engage the gear to lock the same when the pump rod is down, a coin releasable motor ,having an element to actuate said tilting member unlocking said gear to allow the same to be rotated in one direction to raise .the pump rod, said tilting member having, an additional arm to engage'said gear when the member is tilted to release the gear to prevent the gear from being rotatedqn the opposite direction, a device tonal arm as the rod nears the limit of its upward position to tilt said member so as to restore the first arm in engagement with said gear, so that said gear may be operated manually in said opposite direction, said first arm slips by the teeth of said gear when ro- `tated in said opposite direction to lower the pump rod, said first arm constitutes means to lock the gear when the rod reaches its lowermost position, and a collar adjustable on the pump the rod n its downward movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing' witnesses.
